4 * Parses string hash files. File format is as such:
5 *
6 * DefaultKeyValue
7 * KEY: Value
8 * KEY2: Value2
9 * --MULTILINE-KEY--
10 * Multiline
11 * value.
12 *
13 * Which would output something similar to:
14 *
15 * array(
16 * 'ID' => 'DefaultKeyValue',
17 * 'KEY' => 'Value',
18 * 'KEY2' => 'Value2',
19 * 'MULTILINE-KEY' => "Multiline\nvalue.\n",
20 * )
21 *
22 * We use this as an easy to use file-format for configuration schema
23 * files, but the class itself is usage agnostic.
24 *
25 * You can use ---- to forcibly terminate parsing of a single string-hash;
26 * this marker is used in multi string-hashes to delimit boundaries.
